Figure 2.

Three-point bending test of natural bone matrix (NBM) versus decellularized bone matrix (DECBM) of calvaria with a sample size n = 5 (a). Samples were maintained hydrated with PBS during experiment. The strength was decreased by 19.42 MPa after decellularization (P < 0.05). A typical TGA result showed the weight loss versus temperature. Distinct weight drop patterns are attributed to the degradation of water (initial drop in the curve prior to 100°C) and organic materials (second drop at 300) (b).
